Abstract
Abstract Irrigation apparatus including a water supply pipe supported by a plurality of carriages spaced therealong, the carriages having wheels spaced in the direction of movement and on opposite sides of the pipe, and vertically retractable and extendible in response to unevenness in the ground tending to support the pipe evenly, and cables supporting the pipe at a plurality of points between the carriages and from points on the carriages spaced transversely of and on opposite sides of the pipe.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
154 words
Irrigation apparatus comprising, a relatively long supply pipe adapted for connection at one end to a water main, and adapTed for movement in direction generally transverse to its length, a plurality of carriages supporting the supply pipe at points spaced along the supply pipe and supporting it in spaced relation above the ground, each carriage including a pair of frames, and a wheel on each frame, lying generally in a plane transverse to the length of the supply pipe with the wheels spaced a substantial distance transversely of the supply pipe and positioned on opposite sides thereof, yielding means incorporated in the carriage enabling rising of each wheel independently of the other and relative to the body of the carriage in response to encountering a rise in the ground, whereby to limit movements of the supply pipe to an extent less than in the case of a rigid carriage and wheels rigidly mounted therein.
Claim 2
Dependent Claim
154 words
Irrigation apparatus comprising, a relatively long supply pipe adapted for connection at one end to a water main, and adapTed for movement in direction generally transverse to its length, a plurality of carriages supporting the supply pipe at points spaced along the supply pipe and supporting it in spaced relation above the ground, each carriage including a pair of frames, and a wheel on each frame, lying generally in a plane transverse to the length of the supply pipe with the wheels spaced a substantial distance transversely of the supply pipe and positioned on opposite sides thereof, yielding means incorporated in the carriage enabling rising of each wheel independently of the other and relative to the body of the carriage in response to encountering a rise in the ground, whereby to limit movements of the supply pipe to an extent less than in the case of a rigid carriage and wheels rigidly mounted therein.
Claim 3
Dependent Claim
61 words
Irrigation apparatus according to claim 1 wherein the yielding means is operative for enabling yielding movement of the frames in response to vertical movements of the wheels mounted in the respective frames, in response to encountering rises in the ground, and the carriage having means supporting the supply pipe at a point closely adjacent the position of connection between the frames.
Claim 4
Dependent Claim
143 words
Irrigation apparatus according to claim 2, wherein the frames are pivotally interconnected in the form of an ''''X'''' forming a pair of downwardly diverging legs on which the wheels are mounted and upwardly diverging upper extensions of the frames, compression springs mounted between the upper extensions and legs on the opposite sides of the carriage, the frames yielding in response to either of the wheels encountering rises in the ground in response to which the respective wheels rise and cause the frames to move relatively toward a flattened position against the action of the compression springs, whereby to minimize vertical movements of the pivot axis between the frames in response to such vertical movements of the wheels, and the carriage supporting the supply pipe at a point closely adjacent to and vertically fixedly secured in association with the axis of said pivot axis.
Claim 5
Dependent Claim
57 words
Irrigation apparatus according to claim 3 wherein the upper extensions of the frames according to their construction as specified, extend beyond the supply pipe both upwardly and laterally, and the apparatus including supporting cables secured to the upper ends of the respective extensions of the frames and toward the next carriages along and under the supply pipe.
Claim 6
Dependent Claim
47 words
Irrigation apparatus according to claim 4 wherein said supporting cables are non-yieldingly secured to the upper ends of the carriage frames, and also wherein such supporting cables are mounted for relative sliding movement longitudinally of the supply pipe and in direction from one carriage to the next.
Claim 7
Dependent Claim
39 words
An irrigation apparatus according to claim 3 and including supporting cables from the upper extended ends of the carriage frames to the supply pipe at points on the latter less than half the distance to the next adjacent carriage.
Claim 8
Dependent Claim
61 words
Irrigation apparatus according to claim 6 wherein the support cables are rigidly secured to the supply pipe and yieldingly connected to the upper ends of the carriage frames, whereby to effectively change the length of those support cables in response to the carriage frames pivoting relative to each other in consequent vertical and lateral movements of the upper extended ends thereof.
Claim 9
Dependent Claim
52 words
Irrigating apparatus according to claim 3 wherein the upper extensions of the frames extend beyond the supply pipe both upwardly and laterally, and the apparatus including cables connected with said extensions and inclined inwardly toward and secured to the supply pipe and thereby resisting deflection of the supply pipe in transverse directions.
Claim 10
Dependent Claim
25 words
Irrigation apparatus according to claim 8 wherein the supporting cables include certain cables secured to said upper extensions and secured directly to the supply pipe.
Claim 11
Dependent Claim
87 words
Irrigation apparatus as set out in claim 8 in which certain of the supporting cables are secured To said upper extensions in adjacent carriages and also support the supply pipe at positions substantially midway between the adjacent carriages, and whereby upon transverse movement of the ends of said upper extensions, and consequent lowering or raising of the supply pipe supported thereby, the supply pipe in its vertical movements is maintained substantially midway between the ends of said upper extensions and thereby maintained substantially against transverse horizontal deflection.
Claim 12
Dependent Claim
143 words
Irrigation apparatus according to claim 1 wherein each carriage includes a pair of frame members pivotally interconnected on an axis extending generally along the pipe and having upwardly and outwardly extending terminal arms, and self propelling means which includes a gear reducer, an input shaft operatively connected thereto and extending therefrom rearwardly relative to the direction of movement of the apparatus, and having a water wheel on the outer end thereof, water line leading from the supply pipe to said water wheel and having nozzles directed against the water wheel in position for rotating it, means interconnecting the gear reducer and the wheels of the carriage propelling the carriage, the propelling means including a shaft extending rearwardly from the supply pipe, and links suspending the outer end of the shaft from the upper outer end of the respective frame member of the carriage.
Claim 13
Dependent Claim
28 words
Irrigation apparatus according to claim 11 wherein the propelling means incorporates a sprinkler unit including a flexible conduit leading from the supply pipe outwardly to the water wheel.
